Acoustic Foam Strip

At Advanced Seals & Gaskets, we produce strips in a variety of materials one of which is Class O acoustic foam.  We are proud to be able to produce any size and any quantity of Class O acoustic foam strip using a range of machinery including presses, kiss cut machines, oscillating knife (CNC), bandsaws, and for longer lengths (also referred to as foam tape), we can use one of many log cutters.  Manufacturing these strips in-house allows us to provide the best quality strips to our customer's exact specifications such as thickness, width, length, and finish - whether this is plain or self-adhesive, it also allows us to oversee the entire process to ensure that our standards are kept high and lead times are at a minimum.

Class O acoustic foam strips are used in many industries where a flame retardant material with sound/vibration absorption, or thermal insulation properties is required, such as building, construction, marine, and automotive industries

What is acoustic foam?

Class O acoustic foam is just one of many Polyurethane foams, it is an open cell structured, lightweight foam used for sound control, noise and vibration treatment, and as thermal insulation material.  The purpose of acoustic foam is to reduce sound and echo not totally eliminate sound, when used as sound absorption strips in ceilings, walls, and flooring, the material works by attenuating the sound waves, lowering their amplitude to reduce and control the noise whilst the captured energy from the sound waves is dissipated as heat. 

Class O acoustic foam is flame retardant and meets UL-94 V-0 and  BS476 part 6 & 7, it is Non-toxic, HCF & CFC Free doesn’t support fungal growth, is dust-free making it ideal for marine, building and construction, automotive, heating & Ventilation and manufacturing.  Class O acoustic foam is a soft material that is easy to cut and easily manipulated to fit complex shapes and positions for ease of application.

    Strips are usually used as an isolation layer or gap filler between 2 surfaces, which is why it is sometimes referred to as ‘gasket tape’. We manufacture strips using an extensive range of materials such as EPDM, neoprene, silicone, solid rubbers, sponge, plastics, polyethylene, PVC, Polyester, cork, textiles, and many more, using specialist machinery including presses, kiss cut machines, oscillating knife (CNC), bandsaws and for longer strips supplied as rolls, we can use one of many log cutters.

    Our lamination service also allows us to supply strips in greater lengths and thicknesses, with a choice of self-adhesives or foil faces or even laminated to other materials.   

    Why use Acoustic foam strips?

    Class O acoustic foam strips can be found used in most industries including engineering, construction, automotive and HVAC to name a few.

    Class O acoustic foam strips are primarily used for noise, echo and vibration reduction by controlling the reverberation that sound makes when bouncing off the walls and flooring.  As well as the sound absorbing properties, acoustic foam is used in many other applications as the material has high performance in fire protection and thermal insulation, this makes acoustic foam great for use in HVAC, construction and automotive industries where strict regulations apply. 

    The durable nature of acoustic foam allows us to cut strips in thicknesses of just a few mm, and supplied plain or with a range of coverings such as foil, self adhesive or even laminated to other sponge and rubber materials in order to increase the number of uses and properties the strips have.  For further information on the many uses of acoustic foam strips please get in touch and a member of our team will assist you.

    The Advantages of using acoustic foam strips

    There are a great many advantages to using acoustic foam strips for your project, these include excellent flammability standards, noise dampening, and thermal insulation properties making it perfect for building and construction..  It is also a non-toxic,  non-dusting material that doesn’t support fungal growth, perfect for ductwork/ventilation applications and is flexible so easily applied to curved or misshapen surfaces such as around pipes or inside machinery and vehicles.

    Class O acoustic foam as a material helps the automotive and construction industries comply with noise pollution and flame retardant regulations.   As Class O acoustic foam is dust-free and does not tear or migrate when exposed to high pressure airflow, it is a popular choice for air conditioning, filtration and ventilation systems.

    Benefits of acoustic foam strips

    • Grease Resistance
    • Non-toxic, HCF & CFC and Dust Free
    • Oil Resistant
    • Durable
    • Chemical Resistant 
    • Doesn’t support mildew or fungal growth

    Different Grades

    Advanced Seals & Gaskets manufacturer strips in a variety of materials with some acoustic properties, Class O acoustic foam being the most popular where a combination of soundproofing and flame retardancy is required.  It is a lightweight and flexible material excellent for use as pipe lagging, duct lining and studio/engine room/automotive insulation, and much more.
